DUMPINGY-SCOW.

SPECIFICATION forming part OfLGttGrS PQtHt NO. 605,762, dated June 14,1898.

Application filed November 20, 1897. Serial No. 659,262 (No model.) I

To ctZZ whom it ntay concern:

Be it known that I, NATT STIoKNEY, of Bradford, in the county of Essexand State of Massachusetts, have invented a new and ImprovedDumping-scow, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improveddumping-scow which is simple and durable in construction and arranged topermit a convenientdischarge of a load and an automatic return of thereceptacle after the load is discharged, thus requiring little or nomanual labor in the working of the scow.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafterand pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis invention, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a plan view of the improvement, and Fig. 2 is a sectionalside elevation of the same.

The dumping-scow is provided with a body A of any approved constructionand formed with a bottomless well 13, containing one or more receptacles0, each hung at its ends on pivots D, secured to transverse beams orpartitions E, as is plainly indicated in Fig. 1. Each receptacle 0, ismade in the form of a scoop having the discharge end 0 extended such adistance from the pivot D that when loaded it overbalances the oppositeside 0 and consequently the receptacle which receives a load while heldin a horizontal position, as shown in Fig. 2, after being releasedswings automatically into a dumping posi tion, as indicated in.dottedlines in Fig. 2, to allow the contents of the receptacle to flowout over the discharge side 0 and "through the bottom of the well B intothe water below. 'It will be understood, however, that when empty thereceptacle 0 tends to assume the horizontal position shown in full linesin Fig. 2.

In order to hold the receptacle 0 in a normal or horizontal position, asshown in Fig. 2, I providethe top of the scow with a pivoted catch F,adapted to pass under the side 0, so

as to lock the receptacle in place during the filling thereof with theload and while the scow is carried to the place of dumping. When thedumping-place is reached, the operator simply turns the catch F to alloweach receptacleto'swing into a dumping position, as previouslyexplained, owing to the overbalancing weight on one side of thereceptacle.

r The receptacle C can be locked in a dumping position in case the loadis of a sticky nature and discharges slowly, and for this purpose'Iprovide'the bottom of the receptacle with teeth G, adapted to be engagedby a pawl H, fulcriimed to the top of the scow opposite the catch F.WVhen the receptacle swings into adumping position and the pawl H isthrown over. against the peripheral surface of the receptacle, then saidpawl engages one of the teeth G to lock the receptacle in a dischargingposition..

The receptacle may be made of sheet metal or other suitable material,and the well may be lined with a similar metal, as indicated in Fig. 1.

Now it is evident from the foregoing that the load can be quicklydischarged whenever desired, and after the material has left thereceptacle the latter automatically returns to its former position andagain passes under the catch F, which is swung out for this purpose tohold the receptacle in place during loading.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. The combination of the well widened at itstop, and the dumping-receptacle mounted to turn in said widened portionand so arranged j that in the discharging position the .outlet of thereceptacle is within the well and substantially at the lower end of thewidened portion thereof.

2. A dumping-scow provided with a well, open at the bottom, a receptaclepivoted at its ends in the hold, and having its discharge side arrangedto overbalance the opposite side, so that upon releasingthereceptaclefrom a normal position, it will turn automatically on itspivots into a dumping position and-discharge the load, and means,substantially as described, for locking the receptacle in a I means forlocking the receptacle in the disdumping position, as set forth.charging position. (1 3. ljhe combination of the support, the STICKNEYumping-receptacle n10 a-bly mounted the1e- 5 on and constructed with atendency to assume Vitnesses:

the receiving position when einptyand to rock LESTER F. STEARNS, intothe discharging" position when filled, and JOSEPH C. \VHITE.
